M.2 SSD NVMe Enclosure, 40Gbps, Thunderbolt 4

Last crawled date: 1 year, 5 months ago

Supports up to:
40 gigabits/second = 5 gigabytes/second
(Note: 1 gigabit = 125 megabytes)

This M.2 SSD NVMe Enclosure lets you install M.2 size/type PCIe NVMe solid state drives and convert them to an external hard drive.

PCIe NVMe solid state drives are currently the fastest hard drives out there.
What normally takes days or hours to transfer or read/write on a normal spinning hard drive
only takes a few minutes or an hour or two (depending on file size) to read/write on a solid state drive.

The current dominant standard being used for PCIe M.2 NVMe solid state drives is PCIe 4.0.
PCIe 5.0 solid state drives are coming around the corner but are not available yet commercially to the regular consumer as of 12.6.2022.

Tested with this SSD:
SAMSUNG 980 PRO SSD 2TB PCIe NVMe Gen 4 M.2

Genuine PCIe 4.0 NVMe speed (up to 7,000/5,100MB/s for read/write speed)
Ideal for heavy computing, high resolution graphics and PC gaming.

Model No:
MZ-V8P2T0B

It's kind of expensive because it supposedly supports a higher data transfer rate, otherwise I may return it (see my explanation below).
Hopefully it drops in price over time.

The speeds I got were tested via the Blackmagic Design disk speed testing software.
The PC used was an Apple M1 MacBook Pro.
I got speeds of about:
1,875 MB/s Write (~15 gigabits)
2,900 MB/s Read (~23 gigabits)

I may return it since the enclosure chip on the PCB seems to be:
RTL9210B-CG
https://www.realtek.com/en/products/communications-network-ics/item/rtl9210b-cg
This chip may not support the full 40 Gbps (5,000 MB/s) rate the enclosure claims to support, unless it has another chip that supports that rate.
It may only support the below or near the maximum data transfer rate for PCIe 3.0 solid state drives.
